ISAAC I. OASKEY, OF COLUMBUS, OHIO, ASSIGNOR OF ONE-HALF TO MARION L.G-ASKILL, OF COLUMBUS, OHIO.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 785,250, dated March21, 1905, Application filed July 12, 1904. Serial No. 216,250.

To (1/7], whom, it may concern.-

Be it known that I, ISAAC I. OAsKuY, acitizen of the United States,residing at Columbus, in the county of Franklin and State of Ohio, haveinvented certain new and useful Improvements in Oar-Couplings; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.-

' dated September 1, 1903. In the coupling of said patent it may besometimes impracticable to operate the knuckle-lock 3 to permit theuncoupling of, the cars, especially when they are jammed together,without first relieving the jammed condition.

The present invention therefore consists in such a construction of theparts of the coupling referred to as will permit the setting of thecoupling even if the cars are jammed together.

In the accompanying drawings, Figure 1 is a horizontal sectional view onthe plane :12 m, Fig. 3. Fig. 2 is a vertical section on the line 3/ y,Fig. 1, with the knuckle andlock omitted. Fig. 3 is a front elevationwith the knuckle removed. Fig. 4 is a vertical section on the line .2 2,Fig. 1. Fig. 5 is a perspective view of the knuckle. Fig. 6 is aperspective of the lock.

As in the previous patent herein referred to, 1 designates thedraw-head. This has a cavity 1, with the upper part of its rear wall atone side curved inwardly toward the roof of the cavity, as indicated at1, to form a cam toact on an arm ofthe lock to throw reach behind aprojection on the lock, as hereinafter described; but the principaldifference between the knuckle in the present invention and that of theprior patent herein referred to consists in the provision of a cavity 2in the inner wall of the locking-wing.

3 designates the look. This is secured to a vertically-movable pin 1,passing through perforations in the upper and" lower walls of thedraw-head, so that the lock can be raised and lowered. The look, as intheforrner patent herein referred to, is generally a block of angularlever form, the pin .4: constituting the fulcrum. One arm of the lock isformed with a beveled under side 3, adapted to be acted on by thebeveled toe 2* of the knuckle to raise the lock, and a square side 3,adapted to engage the heel 2 on the knuckle when said heel has enteredthe proper distance into the cavity and the lock has fallen into itslocking position at the bottom of the cavity, as indicated in Fig. 3.The other arm of the lock is provided with a rounded inner side 3 to acton the inner wing or arm of. the knuckle and a down ward projection 3 tostand in front of theangular projection 2 of said arm of the knuckle.The right-hand Wall of the cavity is provided in its -lower. portionwith an inward projection 1 having a vertical face 1 and two horizontalseats 1 and 1 the latter being arranged above and to the right of theformer.

The operation is as follows: When two cars are coupled, the knuckles andlocks are in the position indicated in Fig. 1. When the cars are to beuncoupled, the lock is raised and turned slightly to rest on the seatlIt will be observed that the recess 2 permits the lock to rise to be soseated without action of the part 3 on the inner arm of the knuckle andthat one of the knuckles can be turned out by the action of the otherwhen the cars are separated. To throw an unset knuckle into open orcoupling position, however, the lock is further lifted, and when solifted the wall 1 turns the left-hand arm of the lock against the innerarm of the knuckle, and

therefore throws the outer arm into theopen position. The coupling andlocking is automatic whether the lock is resting on the seat 1 or 1 oris resting at the bottom of the cavity. In the first two cases the lockis thrown around by the inner arm of the knuckle into position to dropinto the bottom of the cavity and in the last case it is lifted by thewedge-toe 2* of the inner arm of the knuckle.

In case the pin connecting the knuckle to the draw-head breaks theprojection 2 cooperates With the projection 53 to prevent the knucklefrom pulling out.

What I claim, and desire to secure by Letters Patent, is

1. In a car-coupling, the combination of a draw-head, a knuckle hingedthereto, a lock movable vertically and rotatable horizontally in saiddraw-head adapted to be lifted by the knuckle, and adapted to be liftedindepend-' ently of and Without acting on the knuckle into position topermit the knuckle to be opened, and a seat to support the look when solifted.

2. In a car-coupling, the combination of a draw-head, a knuckle hingedthereto, a lock movable vertically and rotatable horizontally in saiddraw-head adapted to be lifted by the knuckle, and adapted to be liftedindependently of action on the knuckle into position to permit theknuckle to be opened, a seat to support the lock when so lifted, meansfor throwing the lock when lifted ofi said seat into contact with theknuckle to throw the latter into open or coupling position.

3. In a car-coupling, the combination of a draw-head, a knuckle hingedthereto, a lock movable'vertically and rotatable horizontally in saiddraw-head adapted to be lifted by the knuckle, and adapted to be liftedindependently of action on the knuckle into position to permit theknuckle to be opened, a seat to support the lock when so lifted, meansfor throwing the lock when lifted off said seat into contact with theknuckle to throw the latter into open or coupling position and a secondseat for the lock in its further raised position.

4. In a car-con pling of the kind described, the combination with adraw-head having a cam-surface l, the knuckle hinged to said draw-headhaving its inner arm provided with a cavity 2 the vertically-movable andhorizontally-rotatable lock having a member to extend into said cavity 2and act on the inner arm of the knuckle beyond said cavity,

substantially as described.

In testimony whereof I aflix my signature in presence of twowitnesses.
